Sunspots and space weather stormsNews story originally written on October 24, 2003

Two very large groups of sunspots have
appeared on the Sun. Each of the groups is about
as big as the planet Jupiter, which is the largest planet in our Solar System!
Sunspots are places on the Sun where the Sun's magnetic
field is all tangled up. These tangled
magnetic fields create storms called solar
flares and CMEs. Some storms from
these two big sunspot groups reached Earth on
Friday, 24 October 2003.
